Regression in ifort19: seg fault on allocatable array operations

Regression in ifort19: seg fault on allocatable array operations

Unfortunately, there was quite some regression in the beta release of ifort v19 which lets ca. 10 of our unit tests and ca. 20 of our functional tests fail with segmentation faults. We think/hope that this is only one bug/regression. I reported this as support item 03384851 to the Intel Support. Unfortunately, the regression was not yet fixed within the Update 1 of the beta version. Hopefully (fingers crossed) this gets fixed for the official release. In v17 there were many regressions at the beginning so we had to special case our build environment to veto v17.0.0/1/2/3 and only allow v17.0.4 onwards. v18 came with some regression (IIRC) that was fixed, however, before the official release came out. We hope very much that this will happen for v19 as well. Here is the code leading to the problem:

Intel support informed me that this issue has been fixed by the developers, and the fix will be available for the official release of the v19 of the compiler. So that is great news, I am eager to test the official version.
